Spaghhetti:
Spaghetti code is a pejorative term
for source code
Ravioli:
Ravioli code is a type of computer
program structure, characterized by a
number of small and (ideally)
loosely-coupled software components.
The term is in comparison with
spaghetti code, comparing program
structure to pasta;
It’s comparing them. It isn’t saying it’s an anti-pattern.
But I agree. The article is confusing. The problem is not with ravioli analogy but with the wikipedia article structure itself. It starts calling Spaghetti as a bad practice, then says some examples and after that say something about Ravioli code.
EDIT: They improved the article. Is an anti-pattern because
While generally desirable from a coupling and cohesion perspective, overzealous separation and encapsulation of code can bloat call stacks and make navigation through the code for maintenance purposes more difficult.
